[Chemistry Class Notes] on Sorting Material into Groups Pdf for Exam

Daily, we come across so many examples that are unorganized and randomly placed out there. However, they need to be organized in order to work well. If we talk about how to organize or sort them, then we should know that everything can be sorted out properly. What you need to do is just to divide them into groups and then, start sorting.

For example, if you are having a lot of information or things that are different on the basis of importance, then you should start sorting it out accordingly. Keep the most important things in one group, the lesser ones in another group and you can go for keeping the least important things in some other group.

When we look around us, we find ourselves surrounded by a number of objects having different shapes, colors, textures, properties, and uses. Some of these objects are made from a number of different materials, while some are made using the same material. For eg, Both desks and chairs are made from wood while bottles and dustbins are made from plastic. A plastic bottle is used to store water whereas a dustbin is used to collect waste materials. The same material can be used to make different types of objects. For example, glass can be used to make bulbs, screens, bowls, window panes, etc. The same object can be made of different kinds of materials. For example, a table is made of plastic, wood, or iron. So, in order to classify the material as per their usage, Sorting Material into groups is necessary.

In this article, you are basically going to learn how you can sort out different things on the basis of different criteria such as its appearance, transparency, solubility, and so on. To have good information about sorting the objects, let’s have a look at some important points that are going to help you in this process.

Properties of Materials

Appearance

Materials can be classified on the basis of their look or appearance, Some materials have a soft glow to them while others are plain and dull looking. Materials that have a soft glow can be classified as Metals like Copper, gold, aluminum, iron, etc. Besides this, some substances can be small, some tall, or even short. There can be differences in their heights or their structure and other appearance that will enable you to sort the items on the basis of external features or appearance only.

Soluble or Insoluble

The materials that can be dissolved in water are said to be soluble materials. For example, Salt and Sugar can be dissolved in water. Materials that can’t be dissolved in water even after stirring them are said to be insoluble materials. For example, Stones and sand cannot be dissolved in water.

You can go on by trying to dissolve the substances in water; those which are soluble will readily dissolve while the ones that are not soluble will settle down.

Transparency

• Objects or materials which we can see through are said to be transparent objects. Eg: Glass, clear water, and some plastics.

• Objects or materials through which things can be seen only partially are called Translucent objects. Eg: Butter paper, thin plastic sheets, frosted glass, etc.

• Objects from which cannot be see-through are termed opaque objects. Eg: Metals, wood, brick, book, wall, clothes, etc.

On the basis of their transparency, they can be easily sorted and after that, they can be used for further purposes and it will be easy for you to distinguish.

On the Basis of the State of Matter

The above-mentioned table will help you to know about the difference between solid liquid and gas. If you are able to distinguish them then it will be easier for you to use them quickly on the basis of their properties.

Why Do We Need to Sort Materials Into Groups?

(Image to be added soon)

There are certain reasons that require you to sort the substances on the basis of different features and properties. After knowing about the way by which they can be sorted out, we need to find out about the reason for which sorting of material is necessary.

The Main Purpose of Sorting Materials Into Groups is Listed Below:

• Storage: In order to allocate suitable containers for the storage of objects, it is necessary to sort objects into solids, liquids, and gasses. Eg: Liquids such as oil and milk can be stored in containers such as a glass tumbler, but gasses such as nitrogen and oxygen cannot be stored in them while vegetables can be stored in cloth bags.

• Convenience to Store: We try to group objects in such a way that similar objects are kept together in order to make locating them easier. Even in our homes also, we store spices together in the kitchen, and washing products are stored in bathrooms.

• Manufacturing: Sorting of material can be helpful in the manufacturing process. If we want to manufacture bottles to store liquids, we use materials such as glass, plastic, or metal and not cloth or leaves because they will not retain the liquid. Similarly, while manufacturing a table, we can use wood or plastic, and not glass.

• Convenience to Study: We group objects so that it becomes easy for us to study their features. Sorting is also done on the basis of their physical and chemical properties. To get more insight into the topic, we suggest referring to NCERT solutions.

 

Conclusion

Learning about sorting materials in a group can help students in real life for the long term. Students can practice the same to have a sorted life.
